PURPOSE: To classify the cavernous sinus lesions, to describe their radiological findings, and to assess the usefulness of MR compared to CT. METHODS AND MATERIALS: Fourty-five patients with lesions involving the cavernous sinus proved by histological and/or clinical and imaging methods were studied retrospectively and classified into neoplastic, vascular, and inflammatory lesions. CT and MR findings were compared in 21 patients evaluated by both modalities simultaneously according to these 4 categories. RESULTS: Pitiutary macroadenoma was the most common cavernous sinus lesion(42%). Diffuse convex bulging of the lateral wall of cavernous sinus was the most frequent radiological finding(84%), and the others were encasement of the cavernous carotid artery(49%), remodelling of the surrounding bones(44%), and complete obliteration of Meckel's cave(38%), in descending order of frequency. Bulging of the lateral wall of cavernous sinus was equally well demonstrated on both modalities, but encasement or displacement of the cavernous carotid artery and complete or partial obliteration of Meckel's cave were much better delineated on MR than on CT with the ratio of 3.8:1 and 4.6: 1, respectively. Only bone changes were much better demonstrated on CTthan on MR with the ratio of 3.8: 1. CONCLUSION: MR issuperior to CTin demonstrating thecavernouscarotid artery encasement and obliteration of Meckel's cave, but CT is much better than MR in demonstrating bone changes.

PURPOSE: To evaluate the MR findings of brain damage in cerebral palised patients and to correlate it with gestational age and the time of damage. MATERIALS AND METHOD: A retrospective analysis was performed in 40 patients who underwent MR scanning for evaluation of brain lesion in clinically diagnosed cerebral palsy. Authors classified the patients into two groups as premature and full-term and compared MR findings of the two groups. RESULTS: Abnormal MR findings were noted in 28 cases (70%). Five out of 6 patients who had been born prematurely showed isolate periventricular white matter lesions. Twenty-three out of 34 patients who had been born at full-term showed abnormal MR findings. Of these 23 patients, migration anomalies in 7 patients, isolate periventricular white matter lesions in 3 patients, and other combined periventricular subcortical white matter and deep gray matter lesions in 14 patients were seen. At least, 10 patients(43%) of full term group showed abnormal MRI findings reflecting intrauterine brain damage and all 5 patients of premature group showed isolate periventricular white matter lesions suggesting immaturity of brain. CONCLUSION: MRI is thought to be very useful in the assessment of brain damage for the patients with cerebral palsy by recognizing the location of the lesion and estimating the time of damage.

OBJECTIVE: This study was performed to be evaluated the adequacy on DRG classification in Obstetric group and analyzed the difference for medical benefit payment from the insurance and total medical reimbursement according to complication and age in vaginal delivery group and Cesarean section group. METHODS: This study has been analyzed for medical benefit payment from the insurance and total medical reimbursement of patients from University of hospital since Feburary 1999 to December 2000 and the data from Health Insurance Review Agency since Feburary 2001 to July 2001. RESULTS: Since these cases were not reported even 1 case in Korea, there were 113 cases needed to be deleted in DRG classification disease group. In the evaluation of disease severity for DRG classification disease group, there were 11 cases should be added to severe complicating diagnosis, 5 cases should be removed from severe complicating diagnosis, and 6 cases should be added to moderate complicating diagnosis in vaginal delivery and Cesarean section group. Medical benefit payment from the insurance and total medical reimbursement in the group with having severe complication were significantly higher than in the group without complication in Cesarean section group. Medical benefit payment from the insurance and total medical reimbursement in the group with having severe complication in primigravida vaginal delivery group and the group with having severe complication in multigravida vaginal delivery group were significantly higher in the group without complication in primigravida vaginal delivery group and the group without complication in multigravida vaginal delivery group, separately. CONCLUSION: Severity classification system-severe complication, multiple complication, moderate complication, non-complication-should be included in obstetric DRG classification system.

OBJECTIVE: The aims of this study were designed to determine that serum soluble Fas and Fas ligand levels are altered in women with preeclampsia and HELLP syndrome, and to assess the expression of placental Fas and Fas ligand in women with preeclampsia and HELLP syndrome. METHODS: Blood samples were obtained from 31 women with normal pregnancy, 27 women with preeclampsia and five women with HELLP syndrome. Serum Fas/Fas ligand levels were measured by enzyme linked immunoassay. Immunohistochemical stain with polyclonal antibodies of Fas/Fas ligand were used to identify apoptosis. Mann-Whitney test, x2 test, Pearson correlation coefficients and multiple regression test were used for statistical analysis. RESULTS: Both soluble Fas ligand and Fas were detected in the sera of normal pregnancy, preeclampsia and HELLP syndrome. The mean serum level of soluble Fas was 5.83+/-0.37 U/mL in women with normal pregnancy, 10.84+/-0.93 U/mL in women with preeclampsia, and 10.79+/-00.69 U/mL in women with LELLP syndrome. The mean serum level of soluble Fas ligand was 0.59+/-0.03 U/mL in women with normal pregnancy, 0.51+/-0.21 U/mL in women with preeclampsia, and 0.60+/-0.01 U/mL in women with LELLP syndrome. The mean serum levels of soluble Fas were significantly higher in women with preeclampsia and HELLP syndrome than in women with normal pregnancy, but those of Fas ligand were no significant difference in each group. Apoptosis was conclusively demonstrated within placental tissue. The immunohistochemical analysis of Fas revealed diffuse immunoreactive stains were increased in women with preeclampsia than in women with normal pregnancy. But the immunohistochemical analysis of Fas ligand revealed diffuse immunoreactive stains were decreased in women with preeclampsia than in women with normal pregnancy. CONCLUSION: Placental apoptosis and altered expression of Fas and Fas ligand in trophoblast might influence the pathogenesis or pathophysiologic mechanism of preeclamsia. Elevated serum soluble Fas levels is associated with preeclampsia and HELLP syndrome. The source of elevated serum soluble Fas in preeclampsia and HELLP snydrome remains to be determined.

Nocardiosis is usually a subacute infection, which can occur as an opportunistic infections in patients with systemic lupus erythematosus. There are rare cases of nocardiosis concurrent with Mycobacterium tuberculosis. We report a case of intramuscular nocardial abscess concurrent with pulmonary tuberculosis in a patient with lupus nephritis. She has received cyclophosphamide pulse therapies and is receiving oral steroid therapy 3 months ago. After Nocardia farcinica and Mycobacterium tuberculosis were confirmed by PCR and PCR-RFLP, we initiated trimethoprim/ sulfamethoxazole and antituberculous agents. After then, patient was improved and discharged, maintaining the medications.

Genital HPV infection is the most common sexually transmitted infection, but the majority of infections are self-limited. However, persistent infection with high-risk types can cause cervical cancer in women, which is the most common female genital cancer in Korea. In addition, HPV infection is the cause of genital warts and is associated with other anogenital cancers. The HPV vaccine is composed of the HPV L1 protein, the major capsid protein of HPV. Expression of the L1 protein in yeast using recombinant DNA technology produces noninfectious virus-like particles (VLP) that resemble HPV virions. The quadrivalent HPV vaccine is a mixture of four HPV type-specific VLPs prepared from the L1 proteins of HPV 6, 11, 16, and 18 combined with an aluminum adjuvant. Clinical trials indicate that the vaccine has high efficacy in preventing persistent HPV infection, cervical cancer precursor lesions, vaginal and vulvar cancer precursor lesions, and genital warts caused by HPV types 6, 11, 16, or 18 among females who have not already been infected with the respective HPV type. The recommended age for primary vaccination of Korean females is 15-17 years, considering sexual debut and duration of protection of the vaccine. Vaccine can be administered as young as age 9 years. Catch-up vaccination is recommended for females aged 18-26 years who have not been previously vaccinated. Vaccination is not a substitute for routine cervical cancer screening, and vaccinated females should have cervical cancer screening as recommended.

BACKGROUND: Though leptin, the adipocytes-derived hormone, plays an important role in obesity, it can act as a growth factor for several cancers including gastrointestinal malignancies. Based on this background, we investigated whether leptin expression correlated with the clinicopathological characteristics or disease outcome in patients with colon cancer. We immunohistochemically analyzed the expression of leptin in a "colon adenoma-carcinoma sequence" in the normal colon mucosa, an adenomatous polyp and adenocarcinoma tissue, from a surgical resection for each patient. METHODS: We collected samples from 24 patients with a colorectal adenocarcinoma that was removed in either a total colectomy or hemicolectomy, and who presented with an adenomoatous polyp and an adenocarcinoma in the same surgical specimen. Leptin expression was assessed using immunohistochemical methods and was evaluated by grading the staining intensity as 0, +1, +2, +3. RESULTS: Whereas leptin expression was observed in 4.2% (1/24) of the normal colon mucosa, adenomatous polyps and adenocarcinomas showed 33.3% (8/24) and 50.0% (12/24) expression of leptin, respectively (p<0.05), suggesting that leptin expression in the adenomatous polyps and adenocarcinomas was higher than in the normal colon mucosa (p<0.05). There was no significant difference in leptin expression between the adenomatous polyps and adenocarcinomas, statistically. There was no relationship between leptin expression and patients age, sex, BMI (body mass index), cancer stage, and lymph node metastasis. However, the tumor size in the positive leptin expression group was larger than in the negative leptin expression group (5.6+/-2.2 cm vs 3.9+/-1.4 cm; p<0.05) CONCLUSIONS: Since leptin expression in adenomatous polyps and adenocarcinomas was higher than in the normal colon mucosa and leptin expression significantly correlated with the tumor size, leptin might play a role in the development of an adenomatous polyp and an adenocarcinoma in the colon. However, leptin does not contribute to the progression of colon adenoma, and further evaluation studies will be required.

Hydrocolloid dressings have been developed for many types of wound healing. In particular, dressing is a critical component in the successful recover of burn injuries, which causes a great number of people to not only suffer from physical but also psychological and economic anguish each year. Additionally, silk fibroin is the safest material for tissue engineering due to biocompatibility. In this study, we fabricated hydrocolloid dressings incorporating silk fibroin nanoparticles to enhance the efficacy of hydrocolloid dressing and then use this silk fibroin nanoparticle hydrocolloid dressing (SFNHD) in animal models to treat burn wounds. The structures and properties of SFNHD were characterized using tensile strength and Cell Counting Kit-8 assay. The results indicated the structural stability and the cellular biocompatibility of the hydrocolloid dressing suggesting that SFNHD can be applied to the treatment of wounds. To demonstrate the capacity of a silk fibroin hydrocolloid dressing to treat burn wounds, we compared SFNHD to gauze and Neoderm®, a commercially available dressing. This study clearly demonstrated accelerated wound healing with greater wound structural integrity and minimal wound size after treatment with SFNHD. These observations indicate that SFNHD may be an improvement upon current standard dressings such as Gauze and Neoderm® for burn wounds.

PURPOSE: To evaluate the incidence and clinical features of age-related macular degeneration (AMD) in Korea. METHODS: Web-based (www.armd-nova.or.kr) registration was conducted for AMD patients aged 50 or more who were newly diagnosed by retinal specialists in Korea from August 20, 2005 to August 20, 2006. Patient data including ophthalmologic examination, fundus photography, fluorescein angiogram and/or indocyanin green angiogram (ICG), past medical history, behavioral habit, combined systemic diseases were up-loaded. RESULTS: Among finally enrolled 1,141 newly diagnosed AMD patients, 690 patients (60.5%) were male and 451 patients (39.5%) were female. The average age of AMD patients was 69.7+/-8.0. Early AMD was observed in 190 patients and 951 patients had late AMD. Classic choroidal neovascular membrane (CNVM) was observed in 18.6% of exudative AMD patients and 63.4 % had occult CNVM. Subfoveal CNVM was observed in 80.4% of the patients with CNVM. Among the 580 exudative AMD eyes that performed indocyanin green angiography (ICG), 184 eyes (31.7%) had polypoidal choroidal vasculopathy (PCV) and 36 eyes (6.2%) showed retinal angiomatous proliferation (RAP). Age, male gender, smoking, diabetes and hypertension significantly increased the risk of the AMD among Koreans. CONCLUSIONS: Because of the low rate of participation by retinal specialists, definite incidence of AMD was not obtainable. However, the estimated 1-year AMD incidence in the Pusan area of Korea is at least 0.4%. In contrast to Western people, 31.7% of exudative AMD cases were revealed to be PCV and 6.2% were revealed to be RAP. This discrepancy between ethnic groups should be considered in the diagnosis and treatment modality selection of Korean AMD patients.
